Description

The invention relates to a folding sliding wall and a drive and a running rail for this Faltschiebewand.

For separating or designing rooms, for closing room or window openings and for covering fronts and facades wall elements, such as sliding doors are often used, which are attached to slidable along a running rail drives and optionally rotatably supported. Such sliding doors are made for example of transparent glass, wood or metal. Often wall elements are coupled together so that they form in combination a folding sliding wall or a Faltschiebeladen. Single or more combined wall elements are also used in pieces of furniture, especially in cabinets.

In [1], WO 97/49885 , a sliding stacking wall is shown in which two-part guide rails are used for the displacement of wall elements in a parking space, which have a branch in the parking area, from which a straight and a curved rail element are continued. The wall elements are each suspended from two guided in the track rails drives, one of which moves into the straight and the other in the curved rail element. The wall elements are rotated by 90 ° and, for example, parked adjacent to one another on a wall. Therefore, a special rail system is required for the rotation of the wall elements, which may need to be adapted individually to the local conditions.

From [2], product catalog of HAWA AG, "Architectural hardware for sliding shutters", 2006, page 36 , is a fitting for folding sliding shutters with even or odd number of wings known to be installed, for example, on a window front or the outside of a balcony. The wing elements of the folding packages are rotatably connected to each other by means of hinges. Such a folding package can be pushed laterally against a wall or freestanding be used as a visual or windbreak. The displacement, opening or folding of the folding package is done without additional rail element by manual action. In this case, the wing elements are usually rotated at unequal speed, so that, depending on the manual action, each result in irregular folding operations.

From [3], EP2199514B1 , a folding sliding wall is known in which the front-side first wall element and each subsequent pair of wall elements are each connected to a motorized drive. The motors of the drives are controlled so that they drive at the required speed along the track. Further, the motors are coupled to a drive element by means of which the rotatably supported wall elements are drivable, so that a held wall element by means of the drive not only transported at the required speed along the rail, but also can be rotated to perform the parking operation. This device requires a plurality of motorized drives having an advanced drive mechanism and corresponding control.

It should also be noted that a folding sliding wall, which is used in the front area of, for example, a building, is exposed to strong wind forces. This typically results in known devices disturbing noises.

From the EP1085156A1 a sliding vane system is known in particular for balcony glazing, which has a plurality of each pivotable about an axis of rotation wings, of which at least one additionally slidably formed as a sliding vane. The sliding blades are slidably mounted in guide rails on rollers. With the guide rail passable rail-side coupling elements are connected by the sliding blades, which are engageable with a arranged on the axis of rotation of a sliding blade coupling piece and lock the sliding blades against displacement when it is rotated.

From the US6301833B1 and the US7260916B2 Further systems are known with sliding blades, which have a locking element which can be screwed at a parking position in a circular arc-shaped recess.

The present invention is therefore based on the object to provide an improved folding sliding wall, which by means of a drive device or manually operated. Furthermore, a drive and a running rail for such a folding sliding wall must be specified.

The Faltschiebewand should be driven with only one motorized drive, so that a minimal effort for the drive and the control of the folding sliding wall results.

The Faltschiebewand should be sequentially foldable, so that only the unnecessary wall elements can be rotated and parked and the required wall elements are fully functional.

The device should also be designed simply in the parking area and have no additional rail elements.

The individual wall elements should be kept stable, so that even under wind hardly any noise and only a minimal mechanical stress on the device parts result.

The inventive drive should take up little space, so that this, as already known drives, can be slidably mounted within a correspondingly adapted track rail.

The wall elements should also be locked in the parking space without additional drive means and kept stable.

This object is achieved with a folding sliding wall, which has the features specified in claim 1, and a drive for this folding sliding wall, which has the features specified in claim 12.

The folding sliding wall provided for closing an opening comprises at least four wall elements, four wall elements, which are each connected by a connecting shaft with associated drives, which are mounted displaceably in a running rail.

According to the invention, the wall element is non-rotatably connected to the associated connecting shaft, which carries a rotor which is aligned parallel to the running rail in a rotor channel provided therein, which comprises in one or more areas in which the wall element is parked, a gate with at least one rotor chamber in that the rotor is rotatable and held stationary in an orientation transverse to the rotor channel.

In a first embodiment, the link is integrally formed on the running rail or an integrally connected with the running rail link body and extends over the parking area or over the entire track.

In a second embodiment, the gate is formed on a gate body, which is insertable into a mounting channel within the track rail.

If several parking areas are provided, several gate body are provided. If necessary, the gate body can be provided on both sides or on one or the other side of the rotor channel. This makes it possible to rotate a wall element on one side or the other and to secure against displacement in one or the other direction or in both directions.

The rotor channel may lie freely or be delimited by profile elements of the running rail or by the abovementioned connecting piece connected in one piece with the running rail or inserted therein. Basically, the rotor channel forms a real or virtual channel within the track, which is kept free for the transfer of the rotor or the rotors.

The rotor chambers can be produced by bores, which are incorporated in the integrally connected to the running rail, preferably two-piece link body. The rotor chambers therefore preferably form cylindrical openings or segments thereof. In preferred embodiments, in which the wall elements are rotated only in one direction, an asymmetric gate body is preferably provided only on one side of the rotor channel. If the parking area is located at the end of the track and the wall elements are always rotated in the same direction by 90 °, it is sufficient to provide a rotor chamber that provides space for a 90 ° rotation of the rotor.

The rotor can accordingly be designed symmetrically or asymmetrically and provided with at least one rotor head, which can slide or roll along the wall of the rotor chamber or along the gate. Transitions within the gate or between the rotor chamber and the rotor channel are preferably free of edges, so that loads on the rotor head are avoided. If the associated drive to be secured against displacement in one direction and the other, the rotor on both sides of a rotor head, which can be guided along an associated backdrop.

There are provided at least four wall elements, of which, for example, each second is rotatably connected to a connecting shaft which carries a rotor. At least one of the drives comprises two connecting shafts each connected to a wall element, namely a rotor shaft provided with a rotor and a holding shaft.

By means of the folding sliding wall according to the invention, any openings can advantageously be closed off and released again by one or more wall elements, preferably pairs of wall elements. The number of operated wall elements is limited only by the available motor or manual driving force. It is particularly advantageous that usually only one motorized drive is required. With a large number of wall elements it is also possible to reuse a motorized drive after a number of non-motorized drives. For example, openings that connect two rooms within a building with each other, completely or partially lockable. Furthermore, building fronts or facades can be advantageously covered and protected by means of the folding sliding wall according to the invention.

The wall elements can be moved manually or by means of a drive device into the parking area until the rotor of a drive is at the level of an associated rotor chamber and the drive is stopped. As a result, the wall element is rotated with the rotatably held on the rotor shaft rotor. The symmetrical or asymmetrical rotor is thus aligned transversely to the rotor channel, so that the rotor shaft remains stationary but rotatably held in the rotor chamber. The wall element is typically rotated up to 90 ° about the rotor axis and preferably aligned approximately perpendicular to the running rail. The connected via a hinge with this wall element further wall element is nachgestossen and also rotated by the reverse direction of rotation by up to 90 °. Each pair of wall elements associated with a rotor is thus stopped and folded upon reaching the rotor chamber. The wall elements of Faltschiebewand are thus sequentially rotated in pairs and parked. While a couple of Wall elements is folded, the other wall elements that have not yet reached the parking area, aligned in a plane and thus fully functional. The Faltschiebewand can thus cover parts of an opening or a building front optionally.

At the request of the user, rotor chambers can be provided not only in the parking area, but at any points of the running rail, so that the at least one wall element or groups of wall elements can be parked at any point.

In a preferred embodiment, a foot rail is provided, are guided in the corresponding drives, which are connected to the associated wall elements via bottom connecting shafts, which are aligned coaxially with the cover-side connecting shafts, which are held by the guided in the head rail or running track ceiling side drives , The wall elements are therefore on the ceiling side and bottom side optimally guided and rotatable along precisely defined axes.

The folding sliding wall has a front drive connected to the front wall element and one or more central drives connected thereto, which are provided with two connection shafts each connected to a wall element, namely with a rotor shaft and a support shaft. Each central drive requires only one rotor, which is connected to the rotor shaft and serves to hold the drive in the parking area.

For the front drive preferably provided with a drive unit, however, only one support shaft, but no rotor shaft is provided.

In a particularly preferred embodiment, however, the end wall element is connected to a drive, namely a final drive and not struck with a hinge, for example, on a wall or on an end profile. Also this end drive is preferably provided with a rotor shaft and thus held in the parking area by means of the associated rotor until the associated wall element is also aligned parallel to the running rail. This has the advantage that all wall elements can be operated and stabilized in the same way. This is particularly important if the wall elements are locked after alignment parallel to the track in the manner described below and to do a short locking ride.

As mentioned, the central drives are each connected via two connecting shafts with one end of adjacent wall elements. The ends of these adjacent wall elements are rotated against each other, which is why the central drives preferably each hold a protective profile between the ends of the wall elements. The protective profile has on both sides concave surfaces along which the ends of the wall elements are rotatable at a small distance. This prevents manual intervention between the ends of the wall elements. Preferably, the front drive and the end drive are each provided with an end profile, which engages or can engage on the associated wall or in an associated receiving profile in a recess such that a tight seal is present.

In a further embodiment, the track rail is preferably integrally connected to a stabilizing rail, which has at least one passage through which a guide cam, on an associated wall element is arranged to enter a stabilizing channel when the wall element is rotated with the rotor trapped within the rotor chamber.

The fact is used that the wall element is precisely rotated about the rotor axis, which is aligned coaxially to the preferably hollow cylindrical rotor chamber, and the guide cam can be precisely inserted through the passage in the stabilizing rail. Optionally, the passage is associated with a guide element along which the guide cam is inserted into the passage.

Once the guide cam is inserted into the stabilizing rail, the upper edge of the associated wall element or the upper edges of the interconnected by a hinge wall elements are kept stable not only by the connecting shafts, but also by the guide cam. For example, forces acting on wind are therefore absorbed by the guide cam, which is preferably located near the hinge, so that the two adjacent wall elements are each held stably on both sides by the drives and the guide cams. On the other hand, when a wall element reaches the parking area when the folding sliding wall 1 is opened, the associated rotor is in turn rotated and held in the associated rotor chamber. The rotor shaft is again held such that the guide cam, which has a constant distance from the rotor shaft, is at the height of the passage of the stabilizing rail and can escape through the passage from the stabilizing rail.

The guide cam is positioned at the upper edge of the wall element in such a way that it runs precisely within the stabilizing rail when the wall element is aligned parallel to the running rail. The stabilizer rail can be easily configured and, for example, have a downwardly open U-profile. This U-profile and thus the stabilizing rail can also be integrally integrated into the running rail.

So that the end wall element is held precisely when this is aligned parallel to the running rail, this is also preferably provided with a guide cam, which is introduced by a passage in the stabilizing rail. So that this guide cam can not escape from the stabilizing rail again, the end-side end drive must be movable over a minimum distance. For example, the path of the final drive is limited to a few centimeters. For example, a groove with a length of 2-3 cm is provided in the drive body of the final drive, in which engages a connected to the running rail locking element.

In a further preferred embodiment, a support cam is provided on the upper edge of at least one of the wall elements, which rests in the fully folded and / or fully unfolded state of the wall elements on the outside of the stabilizing rail. In each state, the wall elements are thus additionally stabilized by the support cams. The guide cam and the support cam thus stabilize the wall elements, which is why external influences, for example by wind forces, are completely neutralized. This results in a noise reduction during operation of the Faltschiebewand and a relief of the device parts of the drives in particular the rotor shaft and the rotor. Outside the rotor chamber, the rotor thus always remains aligned parallel to the rotor channel, so that no torques have to be absorbed by the rotor shaft.

In the parking area, the drives are stopped sequentially at defined positions where the rotor in question coaxially lies within the associated rotor chamber. After complete parking of the folding sliding wall all rotors are in the associated rotor chamber and are rotated by a maximum of 90 ° relative to the rotor channel. The drives are thus blocked and can not be moved.

The positions of the drives in the parking area are preferably each defined by a stop which is fixed or detachably connected to the rail or by elements such as the drive body of the already retracted drives is formed. The stopper is defined such that each drive provided with a rotor is stopped at a position at which the rotor is located at the level of an associated rotor chamber. In a preferred embodiment, the bodies of the drives are designed such that they themselves form the required stop. In the parking area, the drives in this case are driven so far against each other until the drive body abut each other. The previous drive forms the stop for the next drive. The dimensions of the drives and the distances of the rotor chambers are to be matched in this case.

The connecting shafts are each connected by means of a wall fitting with a wall element such that each connecting shaft is held by a fitting lever outside the plane of the wall elements. The wall elements can therefore be held and turned by fitting lever in front of a front. By a parallel to the rail force exerted on the drives and the fitting lever also results in an acting on the wall elements torque, which is why this automatically when reaching the parking position to be turned around. Thus, a single motorized drive is sufficient to move and rotate the wall elements.

The running track provided with the rotor channel and the rotor chambers as well as the drives provided with the rotor shafts can otherwise be configured conventionally. The drives are provided with running elements and guide elements, such as carrying rollers or sliding elements, which are guided along wings or running surfaces in the running rail. The running rail preferably has two side parts and a middle part, which at least partially form a rectangular cross section. The rotor channel is preferably located immediately below the middle part and may be bounded laterally by profile elements. The rotor shafts are preferably oriented vertically so that the rotor is rotatable in a plane that is perpendicular to the wall elements. The wings for the support rollers are preferably provided on the side parts of the running rail. A guide channel, however, is preferably integrated next to the rotor channel in the middle element of the track.

On one of the side parts of the running rail a mounting channel is preferably provided, in which a linear toothing is provided, into which a gear of a drive unit can engage, which is integrated into the front drive. As a linear toothing, for example, a rack or a toothed belt made of metal or plastic is used. Particularly advantageously, the linear toothing can also be formed in the running rail, so that the linear toothing or the toothed rack and the running rail form a unit. The gear and linear toothing are thus advantageously arranged in a traction channel of the track, which takes up little space. Electrical energy is the drive unit preferably via supply lines fed, which are held in an energy chain. The energy chain is preferably also arranged below the toothed belt in the traction channel, so that for the linear toothing, for example, the toothed belt, the gear and the energy chain of the traction channel can be shared with minimal space.

In this way, motorized drives of the folding sliding wall according to the invention or other sliding door devices can advantageously be supplied with energy without additional space being required.

a part of a folding sliding wall according to the invention, which has only a front drive 5c and an end drive 5A and a mounted slide body 80 without running rail 2.

FIG. 1 shows a folding sliding wall according to the invention 1 with six wall elements 11, 12, 13, 14, 15, 16, the ceiling side and bottom side by means of a running rail 2 and a foot rail 4 out and can be kept stable on the ceiling side by means of a stabilizing rail 3. The wall elements 11, ..., 16 form three pairs 11, 12; 13, 14 and 15, 16, between which protection profiles 18 are provided. The wall elements of each pair 11, 12; 13, 14 and 15, 16 are connected at one end by a hinge 19 and held at the other end by drives 5A, 5B, 5C, which will be described in more detail below. Front and end, the Faltschiebewand 1 on the corresponding wall elements 11 and 16 each have a final profile 18A and 18C, which can be introduced, for example, in a receiving profile.

FIG. 1 further shows that the first pair of wall elements 11, 12 is folded, or oriented perpendicular to the running rail 2. The process for folding the folding sliding wall takes place in the parking area sequentially or in pairs, while the other Wall elements 13, 14, 15, 16 are still aligned in a plane.

The folding sliding wall 1 can be operated manually or by means of a drive unit 61, for example an electric motor. For the operation of the folding sliding wall, ie for the unfolding and filling of the wall elements 11, ..., 16, a force acting on the front wall element 16, for example, by a motorized front drive 5C as in FIG. 2 is shown.

FIG. 2 shows the motorized front drive 5C after removal of the running rail 2. The front drive 5C is connected by means of a connecting shaft or a support shaft 711H to the front wall element 16.

The support shaft 711H is held by a wall bracket 71 which is mounted to the upper right corner of the wall member 16. The wall element 16 is further provided on the upper side with a support fitting 73 which is externally guided along the stabilizing rail 3.

The body 50C of the front drive 5C is further provided with support rollers 51, 52 and guide rollers 53 and at the bottom with a profile holder 180, of which a final profile 18C is held. In the body 50C of the front drive 5C, a motor 61 is further fitted, which is connected to supply lines, possibly data lines, 65, which are supplied via an energy chain 64. The motor 61 drives a gear 62, which engages in a toothed belt 63 which is mounted in the track rail 2.

FIG. 3 shows the folding sliding wall 1 of FIG. 1 with the front drive 5C of FIG. 2 and with a subsequent central drive 5B, which holds two wall elements 14, 15 and therebetween a protective profile 18.

The energy chain 64 is guided directly below the toothed belt 63 in a traction channel 26, which is kept free within the running rail 2. For this purpose, the bodies 50A, 50B, 50C of the drives 5A, 5B, 5C are provided with corresponding recesses or with an inverted L-profile. The energy chain 64 is thus within the track 2 in the traction channel 26, which passes through the drives 5A, 5B, 5C. Within the traction channel 26 and the motor 61 and the toothed belt 63 engaging gear 62 are moved. The entire traction device can thus be integrated into the track rail 2 with minimal space.

In FIG. 3 it is further shown that the two wall elements 15 and 16 connected by a hinge 19 and the wall elements 14 and 15 are separated by a protective profile 18 from each other.

The FIGS. 4a and 4b show the folding sliding wall 1 of FIG. 1 Partly in the parking area with two folded wall elements 11, 12 which are held by mutually driven drives 5A, 5B. FIG. 4a shows the folding sliding wall 1 with and FIG. 4b While the first two wall elements 11, 12 are aligned or aligned almost perpendicular to the running rail 2, the third wall element 13 is still aligned parallel to the running rail 2, so that a part of the opening or front still is covered perfectly. The first and the third wall element 11, 13 are each via a rotor shaft 711R (see FIG. 6 ) connected to the associated drive 5A and 5B. Arranged on each of the rotor shafts 711R is a rotor 712 which is fixedly coupled by the rotor shaft 711R to the associated wall element 11 or 13 and aligned parallel thereto. The two drives 5A and 5B have moved in the parking area against each other, which is why now the third wall element 13 is ready for the rotation or the parking operation.

The FIGS. 5a and 5b show the mutually driven drives from both sides FIG. 4b namely, a final drive 5A and a center drive 5B.

The two drives 5A, 5B, which each have a drive body 50A, 50B, each carry a rotor shaft 711R, which are each rigidly connected to a wall fitting 71. In contrast, only the central drive 5B, which carries two wall elements 12, 13, is additionally connected to a support shaft 711H, which is not equipped with a rotor 712.

The drive bodies 50A, 50B have the shape of an inverted L-profile, with a first vertical profile part 501, a second horizontal profile part 502 and a third vertical profile part 503. The third profile part 503 is provided with a horizontal wheel axle with a first support roller 51 and provided with two vertically aligned axles with guide rollers 53. The first profile part 501 has two horizontally aligned wheel axles with second rollers 52 and bores 55 for the connecting shafts 711, which also pass through the second profile part 502 vertically.

On the upper side of the rotor shaft 711R, which is inserted into a bore 55 of the drive body 50A or 50B, a flange element 7111 is provided, which is supported on the one hand on the upper side of the drive body 50A or 50B and on the other hand a recess for the positive reception of the rotor 712th having. The support shaft 711H is preferably configured identically to the rotor shaft 711R, but is not equipped with a rotor.

The rotor 712 has at each front a rotor head 7121, for example a sliding element or a roller, which extends at least in the parking area along a link 8 and can rotate out of the rotor channel 85 into the rotor chamber 81 and back, as shown in FIG FIG. 7 is shown. Preferably, the rotor 712 is configured symmetrically and in a hollow cylindrical Rotor chamber 81 held. In this way, the rotor shaft 711R is always aligned concentrically with the rotor chamber 81. However, since only a portion of the rotor 712 is required for blocking the associated drive, an asymmetric configuration of the rotor 712 and the rotor chamber 81 can be provided in principle. The gate 8, along which the active rotor head 7121 is guided, is in FIG. 7 shown with a wider line.

The wall fitting 71 comprises a fitting sheet 714 which can be screwed to the wall element 11 or 13 and has a fitting lever 713 oriented perpendicularly thereto, which is rotatably connected, for example screwed, to the associated connecting shaft 711. The fitting blade 714 and the rotor 712 of the associated rotor shaft 711R are aligned parallel to one another. By means of the fitting lever 713 it is possible to keep the wall elements 11, 16, 16 at a desired distance in front of a front. Furthermore, torques are caused by the fitting lever 713, which act on the wall elements 11, ..., 16 and automatically rotate them in the parking area.

Between the two connecting shafts 711R and 711H, the central drive 5B has a holder 180 for a protective profile 18 (see FIG FIG. 6 ), which prevents the manual engagement between the ends of the wall elements 12 and 13. The end drive 5A, however, has a holder 180 for a final profile 18A (see FIG. 6 ), which is preferably retractable into an edge-mounted receiving profile and is preferably always overlapped by this.

FIG. 6 shows the folding sliding wall 1 of FIG. 4b from the back after the partial disassembly of the central drive 5B. The two connecting shafts 711, namely the rotor shaft 711R and the holding shaft 711H, which is configured identically but not provided with a rotor 712, have remained. Stand alone now is the final drive 5A, which has only one rotor shaft 711R with a rotor 712, but no support shaft.

FIG. 7 shows the folding sliding wall 1 of FIG. 6 seen from below with each held in a rotor chamber 81 of the track rail 2 rotors 712 of the drives 5A, 5B, which have been removed from the illustration. It can be seen that the rotors 712 are aligned parallel to the associated wall elements 11 and 13, respectively.

The rotor 712 of the end drive 5A is aligned in the rotor chamber 81 perpendicular to the rotor channel 85 and therefore can not enter the rotor channel 85. The final drive 5A is thus blocked and can only be moved when the associated first wall element 11 is rotated by 90 ° and aligned parallel to the running rail 2.

The rotor 712 of the (first) central drive 5B, however, is aligned within the rotor chamber 81 parallel to the rotor channel 85 and can retract into this. This position is achieved when the central drive 5B enters the parking area and impinges on the end drive 5A or when the third wall element 13 is removed from the parking area and rotated back into the position parallel to the running rail 2. In the first case (entrance), the rotor 712 within the rotor chamber 81 has not yet been rotated. In the second case (exit), the rotor 712 was rotated inside the rotor chamber 81 to the exit position, after which the central drive 5B can extend. At the exit of the central drive 5B, the two first wall elements 11, 12 are now aligned in a position parallel to the running rail, after which also the rotor 712 of the end drive 5A can enter the rotor channel 85. The final drive 5A and the associated first wall element 11 therefore behave the same as the central drives 5B and the associated wall elements 13 and 15. The meaning of this situation is described below with reference to FIG. 10 explained.

FIG. 7 also shows the foot rail 4 from below with a guide channel 41 provided therein, are guided in the guide rollers 53f of the drives 5Af, 5Bf provided on the bottom side. The bottom drives 5Af, 5Bf are also provided via connection shafts 711f (see FIG. 9 ) are connected to the wall-mounted on the wall elements 11, 12, 13 mounted wall fittings 71 f, which are identical to the ceiling-mounted wall fittings 711. The cover side and bottom side provided and mutually corresponding connecting shafts 711, 711f are aligned coaxially with each other, which is why the proper operation of the folding sliding wall 1 is ensured.

The connecting shafts 711 are connected via the fitting lever 713 with the wall elements 11, ..., 16, which is why torques act on the wall elements 11, ..., 16, as soon as a force manually or by means of the drive unit 61 parallel to the running rail 2 on the wall elements 11, ..., 16 is exercised. By the resulting torques, the wall elements 11, ..., 16 are sequentially rotated as soon as the drives 5A, 5B are stopped and retracted with the rotors 712 into the associated rotor chambers 81. Previously, a rotation of the wall elements 11, ..., 16 by the run in the rotor channel 85 rotors 712 and preferably by the reference to FIG. 10 stabilizing rail 3 described below and guide cam 721 guided therein prevented.

In FIG. 7 Furthermore, the end profile 18A and the protective profile 18 are shown with the two concave sides along which the mutually facing ends of the wall elements 12, 13 are guided.

FIG. 8 shows the folding sliding wall 1 of FIG. 4b in turn from the rear side with the wall fittings 71, 71f mounted on the top side and bottom side on the wall elements 11, 12, 13, and the corresponding ceiling-side and bottom-side drives 5A, 5B and 5Af, 5Bf.

FIG. 9 shows the foot rail 4 and the bottom side connected to the wall elements 12, 13 drive 5Bf of FIG. 8 in a detailed view. It is shown that the bodies of the bottom-side drives 5Af, 5Bf form a U-profile, which a provided with guide rollers 53 f part which can engage in the guide channel 41 of the foot rail 4.

FIG. 10 shows the Faltschiebewand 1 with the stabilizing rail 3, which has a plurality of passages 31, which open into a provided in the stabilizing rail 3 stabilizing channel 32. Furthermore, it is shown that on the upper side 10 of the first and the third wall element 11, 13 each a guide fitting 72 is mounted, which has a guide cam 721. Next is mounted on the top 10 of all wall elements 11, 12, 13 and 14 depending on a support bracket 73 which has a support cam 731, by means of which the associated wall elements 11, 12, 13 and 14 can be fixed in the park position.

When the folding sliding wall 1 is closed, the guide cams 721 are inserted through the passage 31 into the stabilizing channel 32 and held displaceably therein. The support cams 731 are positioned in such a way that, after the opening and preferably also after the closing of the folding sliding wall 1, they rest on the stabilizing rail 3, which has, for example, a downwardly open U-profile. Preferably, a guide element 33 is provided, which supports the introduction of the guide cam 721 in the passage 31 and at the same time lets the support cam 731 pass. For this purpose, the support cams 731 are formed, for example, with a lesser height than the guide cams 721. Preferably, the guide cams 721 and the support cams 731 are provided with rollers or sliding elements.

The process of introducing the guide cam 721 arranged on the first wall element 11 into the stabilizing rail 3 is shown in FIG FIG. 10 illustrated.

The rotor shafts 712 are fixed within the rotor chambers 81 at defined positions, but held rotatably, so that the wall elements 11, 12, 13, ... when opening and closing the folding sliding wall 1 always go through the same paths. The guide cams 721 mounted on the upper side 10 of the wall elements 11,..., 16 therefore pass through the associated passage 31 in the stabilizing rail 3 during each turning operation. The constant distance between each rotor chamber 81 and the associated passage 31 therefore corresponds to the constant distance between the two Rotor shaft 711R and the associated guide cam 721.

In FIG. 10 are the rotors 712 of the drives 5A, 5B in the already in FIG. 7 shown alignment shown. The rotor 712 of the central drive 5B is aligned parallel to the rotor channel 85 and can enter into it. The central drive 5B is therefore unblocked and can, pulled by the third wall element 13, extend. In this case, the second wall element 12 is pulled along, which in turn rotates about the hinge 19, the first wall element 11 to the rotor shaft 711R, which is held stationary by the rotor 712 of the end drive 5A. The first wall element 11 therefore performs only one rotational movement until it is aligned parallel to the running rail 2. Like this in FIG. 10 is illustrated, the guide cam 721 passes through the associated passage 31 during this turning operation and enters the stabilizing rail 3. Once this is done, the rotor 712 of the final drive 5A is also aligned parallel to the rotor channel 85 and can retract into it. The final drive 5A is now also deblocked and is pulled together with the first wall member 11 preferably on a locking drive so far forward until the guide cam 721 is held securely in the stabilizing channel 32.

If the first wall element 11 is to remain on the adjacent wall, the travel path of the end drive 5A or the locking travel is limited to a path length which is required to remove the associated guide cam 721 from the passage 31 or within the stabilization channel 32 to back up. After this process, the first wall element 11 on the one hand by the final drive 5A and stably held by the guide cam 721 mounted near the hinge 19, whereby forces acting on the end wall member 11 are also neutralized. This ensures that all wall elements 11, ..., 16 of the folding sliding wall 1 are optimally held and external influences are virtually completely neutralized.

When closing the folding sliding wall 1, the operations described proceed sequentially for each pair of wall elements 11, 12; 13, 14 and 15, 16, which can be freely selected in number. For each pair, a rotor chamber 81 and preferably a corresponding passage 31 in the provided guide rail 3 is provided. A running rail 2 can also be prepared for a higher number of wall elements, of which only a part is used.

When opening the folding sliding wall 1, the described processes run backwards. The rotor 712 of the respective drive 5A, 5B is stopped in the associated rotor chamber 81 and rotated. The associated guide cam 721 is in front of the passage 31 and can escape from the stabilizing channel 32. The associated wall element 11, 13, 15 can therefore no longer be moved, but rotated or parked.

The FIGS. 11 and 12 each show a cross section of the running rail 2 of FIG. 1 , FIG. 12 shows a cross section of the running rail 2 and the stabilizing rail 3 of FIG. 1 seen from the side of the final drive 5A ago.

The running rail 2 has a first and a second side part 201, 202, which are interconnected by a central part 203. At the top between the first side part 201 and the middle part 203, a first support channel 21 for receiving the first support rollers 51 is provided, which are supported on a support and holding element 210, which forms a retaining profile 25 on the underside, in which Timing belt 63 is held. Below the supporting and holding element 210, a traction channel 26 is provided, within which the toothed belt 63, the energy chain 64 with the supply lines 65 and the drive wheel 62 of the drive device 61 are positioned. The traction channel 26 occupies only a minimal space due to the advantageous arrangement of the traction elements 62, 63, 64 and 65. Due to the advantageous use of an energy chain 64 with supply lines 65 provided therein, the use of the otherwise usual busbars is dispensed with. Basically, however, the inventive folding sliding wall 1 can also be equipped with busbars, which from the US7637177B2 are known. Due to the possibility of advantageously arranging the traction elements 62, 63, 64 and 65 in the track rail 2, this embodiment with an energy chain is preferred.

Subsequent to the first support channel 21, a guide channel 23 is provided in the middle part 203, in which the guide rollers 53 are guided. Furthermore, the already described rotor channel 85 is provided with the rotor chambers 81 below the middle part 203. It is shown that the rotor channel 85 is delimited by symmetrically formed gate bodies 80a, 80b, on the front sides of each a backdrop 8 is provided. On the second crank body 80b can be omitted if the rotor 712 cooperates only with the gate 8 on the first crank body 80a. In addition, the first link body 80a, which is integrally connected to the track rail 2, extend only over the parking area. Preferably, the rotor channel 85 is therefore limited in some areas on one side or on both sides.

In the second side part 202, a second support channel 22 is provided with a support member 220, on which the second support rollers 52 are supported.

In FIG. 12 Furthermore, the downwardly open stabilizing rail 3 is shown, the one Stabilization channel 32, within which the guide cam 721 are guided. On the outside of the stabilizing rail 3 are the support cam 731. The closed Faltschiebewand 1 is thus kept stable by the internally and externally applied to the stabilizing rail 3 guide cam 721 and support cam 731.

FIG. 13 shows the front drive 5C of FIG. 2 seen from the other side.

FIG. 14 shows a cross section of the running rail 2 and the stabilizing rail 3 of FIG. 1 from the side of the front drive 5C.

From the FIGS. 12 and 14 It can be seen that the drive bodies 50A, 50B and 50C have an identical cross-section. The front drive 5C differs from the end drive 5A by being equipped with a support shaft 711H and the drive device 61.

The drive device 61 preferably comprises an electric motor and a worm gear, by means of which the drive wheel 62 is blocked when the engine is switched off. The wall element 16 connected to the front drive 5C is thereby kept stable after the drive device 61 has been switched off.

The FIGS. 15a and 15b show the running rail 2 with three therein provided rotor chambers 81 in different spatial representations. For the final drive 5A and two central drives 5B, a rotor chamber 81 is provided in each case. All three rotor chambers 81 are occupied when the three mentioned drives 5A, 5B are subsequently parked in the parking area.

FIG. 16 shows a preferably designed track 2 with a gate body 80 inserted therein, the side of a backdrop 8 with three rotor chambers 81 and two above Holding grooves 84 has. At the middle part 203 of the running rail 2 flange elements 24 are provided, which engage in the retaining grooves 84 and can hold the crank body 80. Thus, a mounting channel 86 is formed between the flange 24, in which one or more link body 80 can be inserted and fixed at appropriate positions, for example by means of screws. For example, screws are used which have a ring cutting edge on the front, which is guided against the central part 203 of the track rail 2 and anchored therein. The gate body 80 shown further, in which the slide 8 is shown hatched, can also be inserted into the mounting channel 86 and fixed at a selected position. As illustrated, the asymmetric gate body 80 requires little space. The rotor channel 85 may be exposed and need not be limited by side walls. Within the track 2 therefore only little space is taken. If necessary, on the other side of the rotor channel 85 also a mounting channel for the assembly of link bodies 80 are provided so that they can be provided on one or the other or on both sides of the rotor channel 85.

FIG. 17 shows a part of a folding sliding wall according to the invention, which has only a front drive 5c and a final drive 5A and a mounted link body 80 without track 2. The final drive 5A is provided with an asymmetric rotor 712, which is screwed into the first rotor chamber 81. Due to the asymmetrical design of the rotor 712 no space is taken on the other side of the rotor channel 85.
